check valves and flame arresters
I'm seeing various systems that use flame arresters and check valves and bubblers. do we all understand correctly how to use them ?

1. "Fame arresters" (victor type) or SS wool located near the engine to prevent back fires these stop the flame by cooling it below ignition by passing it thru a wire mesh or screen ??

2. "check valve" at the reactor which is closed when producing gas and open to atmosphere when no pressure is produced--this is to prevent the vacuum caused by the cooling of the electrolyte from sucking the water out of the bubbler ?

3. "bubbler" acts as a scrubber to remove any Na/K OH that is carried by the gas and also acts as a backup flame arrestor.

It seems to me that we must use all three to achieve a safe HHO gas production ???
IF-- we don't use a flame arrester we could still cause a problem at the bubbler which is filled with gas ,not much, but still explosive.
IF ---we don't use a check valve at the reactor we will suck the water out of the bubbler and eventually over fill the reactor.
IF--- we don't use a bubbler/scrubber we could get electrolyte into the engine.

I think this plumbing should and needs to be discussed so everyone will understand and use it properly.
your suggestions are welcomed

Good luck to all

RE: check valves and flame arresters
Flame arrestors/backfire preventers don't work with hydrogen. The flame speed is so fast that an arrestor can't stop it when propagating back up the line. A bubbler is the only way to prevent backfire to the generator completely.
Most generators aren't making enough volume to be of any great concern anyway, but, a bubbler is all that is necessary to prevent backfire.
